Question

我正在尝试获取脚本列表

我不确定为什么这个错误是 django 抛出的但是，任何人都可以确定是否有问题。

型号

class Script(models.Model):
    name = models.CharField(max_length=100)
    script = models.TextField()

    def __str__(self):
        return self.name

序列化器

class ScriptSerializer(serializers.Serializer):
    id = serializers.IntegerField(read_only=True)
    name = serializers.CharField(read_only=True)
    script = serializers.CharField(read_only=True)

查看；

@api_view(['GET'])
def scripts(request):
    scripts = Script.objects.all()
    serializer = ScriptSerializer(scripts, many=True)
    return Response(serializer.data)

但是当我调用这个视图时，我得到这个错误

Internal Server Error: /api/v1/seo/scripts
Traceback (most recent call last):
  File "E:\folder\venv\lib\site-packages\django\core\handlers\exception.py", line 55, in inner
    response = get_response(request)
  File "E:\folder\venv\lib\site-packages\django\utils\deprecation.py", line 136, in __call__
    response = self.process_response(request, response)
  File "E:\folder\venv\lib\site-packages\django\middleware\clickjacking.py", line 27, in process_response
    if response.get("X-Frame-Options") is not None:
AttributeError: 'Script' object has no attribute 'get'

我也在 Whosebug 中看到了与该问题相关的答案，但无法重现该解决方案。而且这种方法对我来说并不新鲜，我一直在整个项目中使用这种类型的功能。但我现在很惊讶为什么会这样。

编辑：进口

from rest_framework.decorators import api_view
from rest_framework.response import Response
from .serializers import ScriptSerializer
from .models import Script

网址

from django.urls import path
from . import views as views

app_name = "seo"

urlpatterns = [
    path('scripts', views.Script, name='scripts'),
]

Answer 1

我认为这里的问题在于命名冲突。仔细看看这个：

@api_view(['GET'])
def scripts(request):
    scripts = Script.objects.all()
    serializer = ScriptSerializer(scripts, many=True)

名为 scripts 的函数，然后用 scripts = Script.objects.all() 重新分配了此名称。这可能会导致真正意想不到的行为

因此请尝试重命名您的局部变量。即：

@api_view(['GET'])
def scripts(request):
    script_items = Script.objects.all()

UPD 在 urls.py 添加后：

它应该指向函数视图i.o。型号：

path('scripts', views.scripts, name='scripts'),
